Mo Ze Chen didn't even think about how Lin Fan had suddenly summoned these two girls to his side, after all, that wasn't something that could be done with normal people.
For some reason, humans hadn't figured out how to store living beings in storage spaces other than beasts. It was unclear what it was but for some reason, the beasts didn't need oxygen when they were put into the pet storage spaces.
The pet storage spaces that were created by humans lacked oxygen for humans to breathe in, which was the main reason why living beings like humans couldn't stay inside.
But once an expert reached a certain point, they would be able to create a whole world where they could keep people inside, though that was far above the level of this upper realm.
Mo Ze Chen just knew that Lin Fan had some amazing backing, so he must have some kind of special items on him. That was why Mo Ze Chen assumed the two girls were human.
